“…As expected, the most common pathogen was E. coli, followed by Klebsiella pneumonia, Pseudomonas aeruginosa, Enterococcus faecalis and Proteus mirabilis. Generally, this study data is in line with many previous studies (Huang et al, 2014;Sharan et al, 2013;Wang et al, 2014), including the North American Urinary Tract Infection Collaborative Alliance (NAUTICA) study. In the NAUTICA study, forty-one medical centres (30 from the USA and 11 from Canada) participated, the most common organisms found were Escherichia coli (57.5%), Klebsiella pneumonia (12.4%), Enterococcus spp.…”

“…[21] In other countries lower percentages of ESBL producing uropathogen E. coli isolates were remarkable. [23] In this study higher rates of resistance against oral ampicillin, and 1., and 2. generation cephalosporins suggest that they are not suitable candidates for empirical treatment.…”

“…In some studies performed abroad resistance rates to gentamycin ranged between 1.3% (ECO.SENS [13] ) and 63.4% (Gupta et al [5] India). Huang et al [23] could not detect antimicrobial resistance against amikacin, contrary to the findings of Sharma et al [24] (33.3%). In our study higher rates of resistance to gentamycin can be related to widespread use of this antibiotic in the treatment of infections of other systems.…”

Objective: Urinary tract infections (UTIs) are among the most frequently seen community-acquired infections worldwide. E. coli causes 90% of urinary system infections. To guide the empirical therapy, the resistance pattern of E. coli responsible for community-acquired UTI was evaluated throughout a seven-year period in this study. Material and methods:The urine cultures of patients with urinary tract infections admitted to outpatient clinics between 1 st January 2008 and 31 st December 2014 were analyzed. Presence of ≥10 5 colony-forming units/mL in urine culture media was considered as significant for UTI. Isolated bacteria were identified by standard laboratory techniques or automated system VITEK2 (BioMerieux, France) and BD PhoenixTM 100 (BD, USA), as required. Antibiotic susceptibility testing was performed by Kirby-Bauer disk diffusion method using Clinical Laboratory Standard Institute (CLSI) criteria.Results: A total of 13281 uropathogens were isolated. Overall E. coli accounted for 8975 (67%) of all isolates. Resistance rates of E. coli to antimicrobial agents was demonstrated to be as follows: ampicillin 66.9%, cefazolin 30.9%, cefuroxime 30.9%, ceftazidime 14.9%, cefotaxime 28%, cefepime 12%, amoxicillin-clavulanic acid 36.9%, trimethoprim-sulfamethoxazole (TMP-SXT) 20%, ciprofloxacin 49.9%, amikacin 0.3%, gentamycin 24%, nitrofurantoin 0.9%, and fosfomycin 4.3%. There was no resistance to imipenem nor meropenem. The frequency of ESBL-producing E. coli strains was 24%. Conclusion:It is concluded that fosfomycin and nitrofurantoin are appropriate empirical therapy for community-acquired UTI empirical therapy, but the fluoroquinolones and the TMP-SXT shall not be used in the emprical treatment of UTI at this stage. In conclusion, as resistance rates show regional differences, it is necessary to regularly examine regional resistance rates to determine the appropriate empiric antibiotic treatment and national antibiotic usage policies must be reorganized according to data obtained from these studies.

“…A retrospective analysis of Ironmonger et al [7] reveals that gentamicin susceptibility of E. coli isolates from urine samples of patients from the community and from hospitals, for the period 2010-2013, in the United Kingdom, was high, with the resistance rate being 5-7% for the community isolates. Huang et al [6] also studied the antimicrobial susceptibility pattern among E. coli isolates from UTIs, including community-acquired infections in Taiwan, in 2012. They also found the highest sensitivity to amikacin (> 99%), while a lower susceptibility was seen to gentamicin (63.5%).…”

“…Urinary tract infections (UTI) are a major clinical problem all over the world [1,6,10,14]. In this regard, nosocomial UTIs are the most prevalent healthcare-associated infections, but community-acquired UTIs occupy the second place after respiratory tract infections.…”

World-wide, urinary tract infections (UTIs) are an important clinical problem. In such, the most frequently isolated uropathogen is Escherichia coli. In the treatment of uncomplicated UTIs, e.g. cystitis, the widely used antibiotics are nitrofurantoin, trimethoprim/sulfamethoxazole, fosfomycin trometamol or ciprofloxacin, while the treatment of pyelonephritis requires the usage of antibiotics with a broader spectrum of activity, such as cephalosporins of the 3rd and 4th generation, aminoglycosides or even carbapenems. The aim of this study was to assess the susceptibility to aminoglycosides (such as amikacin, gentamicin, netilmicin and tobramycin) of E. coli isolated from UTIs in adult community patients living in Lubelszczyzna. We found that all of the 86 strains of E. coli encountered were susceptible to amikacin. Moreover, the prevalence of susceptibility to tobramycin, gentamicin or netilmicin among the tested strains was found to be 89,5%, 90,7% or 94,2%, respectively. The data obtained in the present study shows the high susceptibility to aminoglycosides of E. coli isolated from the community-acquired UTIS in adults. These data, together with that derived from current literature, indicate that aminoglycosides, when employed in combination therapy with other antibiotics, may still be very useful group of antibacterial agents in the treatment of UTI’s in Poland.
